Have you measured you piston at the proper location (need a book for this) and the cylinder bore at the wear area just down into it a little way (about 1/4") to check for wear?

Just got back from the machine shop. This guy really seems to know his stuff. He took some measurements and determined that I need to go "10 over" with new pistons and rings.

Here's a picture of one of the cylinders.

The bore tool had been run through this one or two times.

He also said the vertical grooves are probably the reason I was getting so much oil coming from my air cleaner.

I also ordered a Haden Oil Fix kit that I won't be using.

Both of my jugs had these copper tubes inserted into the holes that were tapped.

Inquire and make sure they use torque plates when they bore and hone the jugs.

The pics I posted were with the jugs in the torque plates.

Thought you were doing all the work in your garage. I assume your pictures are the before he is going to bore .010 and then re-hone for the crosshatch. Interesting how they look. Scuffing is normal for an unbuttoned non teflon piston old style piston but the crosshatch in the no wear areas does not look original factory. If that is the cylinders after they have been reworked, they sure have not been rebored .010 over.

Correct.

He had just run the honing tool through them to remove the glaze.

More pics to come.....
